在表示一个被动动作时，如果这个动作正在进行，或是与谓语表示的动作同时发生，我们可以用现在分词的被动形式。
【例如】
: X1 {+ e. o; cThe bridge being built now will be completed in three months.This is one of the experiments being carried on in our laboratory.
9 i3 B6 h6 U0 L1 L/ s; w( c( XBeing surrounded by the students, the teacher was answering questions one by one.
% p' S2 x) C. J1 ~) X3 WIf I correct someone, I will do it with as much good humor and self-restraint as if I were the one ____. (CET-4 1996,6)
A) to correct B) correcting C)shavingscorrected D) being corrected
* l, s$ Y3 j, o. c, _句意为：如果我批评某个人，我会尽量保持幽默，自我控制，像批评自己一样。one为代词，后面的动词为其修饰成分，故用分词，而且one与correct之间是动宾关系，故用分词被动式，答案为D。
